Remote Connection to a Server (Windows RDP and Linux SSH)

This guide explains how to connect

to a Windows server via RDP*, and

to a Linux server via SSH*

from Windows, using either PuTTY or the Command Prompt (CMD / PowerShell),

and also how SSH key-based authentication works if it was configured during the server rental process.

Connecting to a Windows Server via RDP

1. Opening Remote Desktop Connection

Press Windows + R*

* Type:

  mstsc

Press Enter*

or on an English Windows system

Press the Windows* key

* Type:

  Remote Desktop Connection

Press Enter*

2. Entering Connection Details

In the Computer* field, enter:

the server IP address* (e.g. 172.17.172.1)

(Recommended: WireGuard setup on VPS)*

Click Connect*

3. Authentication

* Enter:

Username:* Administrator

Password:* the password received via email

* After successful authentication, the server desktop will appear

4. Common Issues

The computer can’t be reached*

→ Check whether the virtual machine is running

→ Verify that RDP (TCP port 3389) is enabled

Access denied*

→ Verify user permissions

Connecting to a Linux Server via SSH (PuTTY)

1. Downloading PuTTY

* Download from:

https://www.putty.org/

After installation, start the PuTTY* application

2. Entering Connection Details

In the Session menu:

Host Name (or IP address):*

  <VPS_IP>

Port:*

  22

Connection type:*

  SSH

Click Open.

3. Login (Password-based)

login as:* → username (e.g. root)

password:* → password

Connecting to a Linux Server via SSH (CMD / PowerShell)

1. Opening Command Prompt or PowerShell

CMD*:

* Start → cmd

PowerShell*:

* Start → powershell

2. Using SSH (Password-based)

ssh root@<VPS_IP>

3. Confirming First Connection

On the first connection, you may see:

Are you sure you want to continue connecting (yes/no)?

Type:

yes

Then enter the password.

Connecting to a Linux Server Using SSH Key Authentication (Passwordless)

If an SSH public key was provided during the server rental process, the server will not ask for a password and will authenticate automatically using the key.

1. SSH Key Authentication via CMD / PowerShell

If the private key is stored in the default location (~/.ssh/id_rsa):

ssh root@<VPS_IP>

If you are using a custom private key file:

ssh -i C:\Users\Username\.ssh\vipy_key root@<VPS_IP>

With correct configuration, no password will be requested.

2. SSH Key Authentication Using PuTTY

When using PuTTY, the key must be in PPK format.

Steps:

1. Start PuTTY

2. Navigate to:

   Connection → SSH → Auth → Credentials

3. In Private key file for authentication:

* select the .ppk private key file

4. Return to the Session menu

5. Set:

* Host Name

* Port (22)

* SSH

6. Click Open

If configured correctly, you will be logged in without being prompted for a password.

3. Important Notes About SSH Key Authentication

The key is installed during the server rental process*

Only clients that possess the private key* can connect

* If the key is lost, a new key must be uploaded via the control panel or directly on the system

Multiple SSH keys* can be associated with a single server

Common SSH Errors

Connection refused*

* SSH service is not running

* Incorrect port is being used

Permission denied (publickey)*

* Incorrect or missing SSH key

* Wrong username

* Invalid or missing private key

No route to host*

* VPN / WireGuard is not active

* Network connectivity is missing
